  1. 1. Aerodynamics of two trucks driving in close-proximity

    Författare :Johannes Törnell; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drag; aerodynamics; cab over engine; inter-vehicle distance; lateral offset; side wind; truck; platooning; yaw; close proximity; wake;

    Sammanfattning : There are several factors driving the development of vehicles with higher efficiency in society, chief among them are the emissions of greenhouse gases and their contribution to global warming. Therefore, there is a strong incentive to improve heavy-duty trucks' energy efficiency, supported by new legislation. LÄS MER

  3. 2. Aerodynamics of vehicle platooning
